An accumulating body of research identifies the importance of landscape structure for a wide range of countryside interests. Landscape structure reflects the results of policies and practices, and is well-suited as a target for management actions. New landscape metrics represent a potential for indicator-based management, provided such metrics relate consistently to the landscape values of interest. In this paper we propose that aspects of landscape structure, specifically heterogeneity, may be related to landscape-based values such as biodiversity, cultural heritage and human appreciation. Birds and vascular plants correlated well with our index for the heterogeneity of land types, whereas insects did not. Occurrence of prehistoric graves was also associated with land type heterogeneity, though other types of cultural remains were not. Landscape experience seems to be associated with the heterogeneity of landscape space rather than heterogeneity of land types. Different aspects of heterogeneity, scale, and variation over time all contribute to explain how our measures of landscape-based values vary in their relationship to landscape heterogeneity. Successful integration between disciplines in landscape studies depends on having a common operational framework, a shared theoretical basis, and a harmonised approach to data collection.

Abstract
Agriculture in Latvia has been going through major reforms since 1991. State farm ownership exists only in a negligible quantity only for research and training purposes and most of the land has been returned to its previous owners, or their descendants, from the times before collectivization. During the Soviet period a number of collective farms were established. Most of these still exist, but the legal form has been changed and they operate on private owned land. Also new ones have been formed. As a result of the agricultural reforms, the accounting, tax and statistical systems that had been established in the old structure were no longer applicable. An urgent need thus arose for the development of new systems for the large number of new family farms. NILF became involved in this work on initiative of the Agricultural University of Norway (NLH), which at that point was cooperating with the Latvian Agricultural University, and was already planning several projects in Latvia in 1993. In cooperation with the Latvian State Institute of Agrarian Economics (LVAEI), NILF was to assist in the development of systems for collecting and making use of financial data for individual farm management and the development of Latvian agricultural policy. The project received financial support from the Ministry of Foreign Affairs' Program for Cooperation with Central and Eastern Europe, and got under way in the summer of 1996. A project unit was established within LVAEI, which was responsible for all work regarding farm statistics. This included the establishment of farm statistics, adaptation to the European Union's Farm Accountancy Data Network (FADN), as well as systems for farm planning. The adaptation to FADN received some support and training assistance from a Danish project. NILF's project constituted the major part of the LVAEI project unit, both with regard to work load and funding. From the Norwegian point of view, the cooperation with the Latvian project unit functioned extremely well, and the unit has continued following the completion of the project. [...]

The World Trade Organization (WTO) will initiate negotiations on the further liberalization of the global trade with agricultural commodities by the end of 1999. These negotiations are basedon Article 20 of the Uruguay Round’s Agreement on Agriculture, which states, inter alia, that the reform process is to be continued, with the long-term objective of substantial and progressive reductions in the support and protection of the agricultural sector. In this context, however, a number of issues are to be taken into consideration, including the so-called non-trade concerns. The Norwegian authorities have started preparations for the new round of WTO negotiations, and have placed substantial emphasis on the non-trade concerns. Norwegian agriculture is regarded as being a ”producer” of more than just food and fibres, for example, national food security, viable rural areas and environmental benefits. The term ”Multifunctional Agriculture” is being increasingly applied to describe these additional functions1. With regard to Norwegian agriculture, it will be of major importance for Norway that sufficient consideration is given to the non-trade and other concerns during the next round of the WTO negotiations. In the summer/fall of 1998, the Norwegian Ministry of Agriculture initialized an evaluation program in order to survey and analyse a number of issues in relation to ”multifunctional agriculture”. The present report is one of the contributions in this context.
Abstract
This report was written in connection with the preparations of the Norwegian authorities for the new round of WTO negotiations on further liberalization of world trade. The report surveys the natural conditions in Australia, France, New Zealand, Norway and the USA, and studies their influence on agriculture, e.g., on farm size, farmland distribution, types of production and production costs. However, it is not easy to limit the analysis to merely the natural conditions for farming, since a number of other political, legal, economic, historic and cultural factors also determine the conditions for agriculture in a country. The report includes agroclimatic data such as length of growing-season, temperature sums, mean temperatures and mean precipitation. Not surprisingly, the climate in Australia and New Zealand is significantly different from the climate in Norway. In these two countries, low temperatures are not a major growth-limiting factor, as they are in (parts of) France, Norway and the USA. Especially in Australia, growth is mainly limited by too high temperatures, excessive radiation, evaporation and lack of rainfall. [...]
